MOVING-PICTURE MACHINE.

Application filed July 26, 1916, Serial No. 111,416. Renewed June To all whom it may concern Be it known that I, EDWIN J. HADLEY, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented a new and Improved Moving- Picture Machine, of which the following is a full, clear, and exact description.

This invention relates to moving picture machines and has for an object the provision of an improvedarrangement for causing the film to be moved through the mach1ne with a minimum amount of injury thereto while giving a maximum exposure.

Another object in view is the provision of a presser for pulling the film through the apertured plate.

A still further object in view is the provision of a rotary presser for pulling the film through the machine and an arrangement of guiding pulleys coacting therewith whereby the cam on part of its movement will pull the film and the remaining part of the movement will take up the slack so that the presser at the beginning of the pulling move ment will not strike or injure the film.

A still further object of the invention is to provide in a moving picture machine a presser and parts associated therewith for pulling with an even strain on the film and means for operating the presser and film so that the film will be moved in proper time and also the framing device without changing the operation of the presser or of any of the parts associated therewith.

In the accompanying drawings:

ably cast integral with the base 2, said base and upright forming a frame for supporting the various parts of the device. Connected with the upright 1 by screws or in any suitable manner is an apertured plate 3 which is provided with any suitable means 4 for holding the film 5 in proper position so that light extending through the aperture 6 may project a picture on the screen. Immediately below the plate 6 is a pin 7 carrying roller 8 over which the film passes, and from thence the film passes under the presser 9. From presser 9 the film passes over a roller 10 arranged on pin 11. This provides a loop extending downwardly between'the rollers 8 and 10 in which the presser 9 operates. From the roller 10 the film passes beneath the extension 12 of the framing device 13 and finally over the take-up sprocket wheel 14. If the film extended directly from the roller 8 to the sprocket wheel 14 no loop would be provided for accommodating the presser 9 and, consequently, the film would be injured by the presser striking the same, but by the arrangement shown an easy smooth movement is produced by reason of the fact that one part of the presser is always in contact with the film and causes an easy contact for the remaining part of the film.

The presser 9 is mounted upon a shaft 15, which shaft causes the presser to rotate at any desired speed, the ratio at which the parts have been coupled in the drawing being such as to cause the presser to rotate sixteen times to one rotation of the crank 16. In forming the presser 9 the particular shape thereof is very desirable in order to give a proper pull to the film and at the same time prevent the presser from striking against the film in such a way as to injure the film. The head or pulling end 17 of the presser is provided with one or more rollers 18 to take up any friction which may be produced at this point, .while the opposite end or tail is rounded at 19. The presser is provided with Y a slightly rounded surface 20 on one side and also a slightly rounded surface 21 on the op posite side in order that the contact of the presser in its movement may be gradual.

The shaft 15 of the presser 9 is so located with respect to the guide roller 10, that when the head 17 begins to pull the film downward, the presser is in engagement with the film throughout its entire length, as shown in Fig. 1, so that the strain upon the film is distributed upon a large surface end 19 will remain in contact therewith until the end 17 has again been brought into contact and produced the pull as shown in Fig. 1. In this waythe presser gradually is brought into contact with the film and gradually moves away from the film at one end so that there will be no sudden jerking or striking of the film. In addition, the movement of the film is very quick as the pull is for only a. very small part of the rotary movement of the presser, whereby the film is stationary for a large part of the time and, consequently, more light may be thrown on to the screen. This allows the use of a four bladed shutter if desired and yet allows the usual or more than usual amount of light to be thrown on to the screen.

As shown particularly in Fig. 1, the sprocket wheel 22 acts as the feed wheel while the wheel 14 acts as the take-up wheel, the parts being so connected together by gearing that the peripheral speed of both wheels will be the same. It will be observed that the shaft 15 which carries the presser 20 also carries a pinion 23 and a spiral gear 24, the spiral gear meshing with a gear 25 which is rigidly secured to the shaft 26 carrying a shutter 27. The pinion 23 meshes with a large gear 28, which gear is connected to shaft 29 to which also is connected the take-up sprocket 14 and a pinion 30. An idler 31 connects pinion 30 with a driving gear 32, said driving gear being rigidly secured to shaft 33, said shaft carrying crank 16 and also a beveled gear 34, as shown in Fig.6. The beveled gear 34 meshes with pinion 35, which pinion is rigidly secured to shaft 36 carrying a beveled gear 37 at the upper end, which in turn meshes with a pinion 38 mounted on shaft 39 carrying the feed sprocket 22. These various sprockets are made of the proper size'for producing the proper turning and are all arranged on the opposite side of the.

upright 1 of the film to the presser 1 and associated parts except the gears 24 and 25. In operation the film is placed in position as shown in Fig. 1 and the rod'40 is pulled or pushed, as the case may be, for movin the arm 41 of the framing device 13, sai framing device being pivotally mounted on shaft 11 and held against movement by friction. The framing device 13 is provided ing device will move the pulley 10 one way I or the other so as to take up to a certain extent part of the film and thereby act as part of the complete take-up device. The framing device 13 has been described and shown as the framing device proper, but it will be evident that the arrangement of the cam 42 forms part of the framing mechanism and could be made to give a sufficient movement to frame the entire pic ture without member 13. The member 13, however, is desirable as it, together with the pulley 10, takes up practically all of the pull or jerk of the film whereby the teeth of the take-up structure will not have any tendency to tear the film. This arrangement of framing device will not in any way injuriously affect the action of presser 9 and will also not in any way affect the movements of either the feed sprocket 22 or the take-up sprocket 14.

The guiding pulleys 8 and 10 may be of any suitable construction having proper guiding flanges and also grooved portions as now commonly used so as to prevent the scratching of the picture. It will be observed that the arrangement as shown in Fig. 1 is very desirable as it produces a 100 in which the presser 9 may operate, the pui leys or guiding members 8 and 10 being above the cam so as to cause a proper operation of the presser regardless of the particular location of the take-up wheel 14. Upon the rotation of the presser 9 as illustrated in Figs. 1 to 4, inclusive, the same moves the film down intermittently and keeps the film on the striking or contacting surface of the presser, thus avoiding the usual pounding of the ordinary beater movement. The action of the cam 42 will cause the pulley 10 to take up or let out part of the film, the same being assisted by the take-up member 13, the action of these members preventing the film from a destructive back pull against the lower sprocket teeth. The arrangement of the taper of the presser tail or upper part 19 permits of almost a one to seven down pull movement, which in turn permits a long release giving the film a long rest in the aperture and thereby causing a greater amount of light to be projected on the screen.
